SteveG celebrates the Jaeger-LeCoultre Master Ultra Thin (MUT) with Caliber 849, highlighting its enduring appeal as a perfect dress watch. His post showcases a platinum version with a slate-blue sunburst dial, emphasizing the movement's reliability and the watch's practical robustness despite its ultra-thin profile. This discussion invites collectors to appreciate the MUT's blend of elegance, engineering, and historical significance.

Certainly not as small as the wonderful Caliber 101 posted below, but just as certainly in the established tradition, the
ultra-thin Cal. 849 originated in 1994 and is 9 lignes (about 21mm) and a mere 1.85mm thick.  Like the 101, JLC have not just
 created a miniature movement, they have managed to make it reliable and practical, in this case fitting it into a 5.4mm thick
watch designed specifically to support such a thin movement and protect it from bumps, bending and even water (the watch is
 rated 5 atmospheres!).


Recently back in the spotlight as a result  of being alternately supersized and automated, the original Master Ultra Thin
remains pretty much a perfect dress watch, with an elegant time-only display, gorgeous and well-engineered case, and a
movement designed and finished to a far higher standard than most.  This platinum version dates from 2001 and sports a
deep slate-blue sunburst dial and pleasant heft for such a waferine watch.


A much more thorough and technically informed review was posted by ei8htohms ( click here ) several years ago, I highly
recommend it!

Great to see this MUT

Thanks for posting these gorgeous photos of the original MUT 34 mm. This model still gets to me. I have waffled on the MUT because of it size, which is small by today's standards. But I am unsure of how I feel about the recasing of the amazing movement in the 38mm case. I think I would prefer the original casing if I can convince myself it is not too small. Clearly I need to try this one on in the 34mm size. In any case, these photos make me drool. In particular, we do not get to see the platinu

Thanks very much, respo! Regarding the size,

YMMV of course, and my wrist is fairly small (6.5") but relatively wide and flat... (& yes, the watch is mine) The 34mm size has some benefits, being that the movement was designed along with case, so it is perfect fit (rather than IMO too small), and also the proportions of the watch are really wonderfully synchronized, diameter, thickness, lugs, bezel...they all work together beautifully! Also, the open and uncluttered dial and narrow bezel make the watch wear larger than its diameter would su

I agree!

I find myself wearing the watch beyond for the 'dress' occasion (at least for my model/color). It is really quite versatile and never a problem requiring that special shirt for the sake of the cuff size.

MUT Size...

Hi Respo, At 34mm Ø the MUT sounds and indeed is relatively small by todays standards. However, it is perfectly proportioned and I class it at the perfect dress watch. I understand why JLC now offer this watch in larger case sizes, but for me this was not necessary and the 34mm model will always remain THE MUT to own. Just my personal opinion of course Cheers David. PS: It does wear slightly larger than 34mm, because of the thin bezel. Worth trying on if you are in the market for a dress watch.

I agree with you, David

I do think the 34mm is THE MUT to get. I have tried on the 38mm and it is a beauty, but the 34mm is the original size designed to house the 849 movement, so it still seems like the way to go. The proportions are just right, the movement does not seem lost inteh case, etc. etc. It is one of those examples of a perfect dress watch. I love the minimalism of it. This is turning into a nice thread with people shoiwing off their MUTs. I hope more people and photos show up. By the way, I just sent you

Well, David

I coppared both of the 34 / 38 mm versions, and I find both of them appealing. The 38 mm is maybe easier to wear, even if the 34 mm is not that hard to wear, due to the fact that the aperture of the dial is really important. The important thing is that the bigger size of the new MUT is not going with a too thick case. yes, it is also thicker than the old MUT ( which is still in production ), butthe volumes are well kept, to me. Best, Nicolas
